Review: Buy Cheap, Buy Twice - I regularly go off-roading in California's deserts and wanted a reliable way to add pressure to my tires when returning to the pavement, and to reinflate tires after a repair. I purchased this compressor in 2010 after my cheap, barely adequate $25 "tire inflator" from a department store chain stopped working. I have had zero problems with my Viair. Uses: In addition to the uses above, I use the compressor every couple of weeks to top up one of my tires that has a slow leak. I just used it to quickly top up the tires on my wife's van. I have also used it to inflate my kid's wading pool via an extra attachment that came with our bicycle pump. Pros: Well made and reliable Easy to connect to the red battery terminal and ground via the alligator clips Positive latching on to the tire stem Pretty fast inflating of even large tires Consistent readings from the integral tire gauge Packs up into a relatively small package that can stay in any vehicle 24/7 Carrying case is handy and makes storage easy Cons: Gets warm after a couple of tires and needs to cool off before packing it up The coiled hose offers a lot of resistance, making reaching the last tire a struggle Getting the compressor back into its case takes a little work Bottom line: Good piece of gear at a fair price point. An additional bonus is that I can forever skip the quarter-fed, nasty gas station air stations that seems to pump as much moisture into my tires as air.
Review: Great tire inflator. Quiet, fast, small and easy to pack. - I was wanting a better quality tire inflator to carry in my Travel Trailer. It had to easily inflate my trailer tires that are rated for 80psig. I read over the reviews of several inflators and decided on the 300P. Put it to the test yesterday. I am very pleased. Had no problem handling the 80psi tires. Pumped one that was at 70 psi up to 80 in about 65 seconds. The battery clips are plenty large enough to grab onto a battery post connector. My trailer batteries are located front underside of my 34 foot 5th wheel center compartment. With electric wire and coil air hose, I reached tires with no excessive stretching. The air hose to valve stem clamp is very good and tight. No air loss and would be much easier than the screw on fittings others come with. This unit also has the "Air release" feature to let out excess pressure. The air gauge is a good quality. The pump is much quieter than I thought it would be. Comes with a very good carrying bag that has room to include any special fittings you may need. I did have my trailer plugged into electric power when using the inflator. The write up on it stated to have vehicle running while using. This is to give the 12V a little extra boost. This is understandable. The in-line electrical fuse would make it very easy to replace fuse if needed. I will be buying an extra fuse to carry just in case.

## Questions & Answers

**Q: does the hose it comes with attach to the tire either screw on or other?**
A: This Compressor set up comes with everything you need and the hose comes with an air chuck on it..and attachments forairing up air matress, balls, etc.  if your going to air up all tires if you let the air out for being in sand give it some time to cooloff inbetween each tire, it does a great job! its not a shop compressor with a big air tank but it is faster than most portable units. its been a great tool to have since I go way out on hunts in the boonies and helped out a few stranded peopleand had a tire plug kit handy as well. good way to earn some 12 packs!

**Q: Can the psi be controlled to a constant 40psi in order to blow out RV water lines for winterization?**
A: With an external regulator, yes. Google RV Geeks Winterizing and go to t=40 seconds to see their solution when using a 150 PSI Viair compressor to blow out their RV water lines. (Sorry, Amazon won't let me post the link here).

**Q: It states it has a 1 year warranty! Yet, no returns. How does the warranty work?**
A: I don't know. It's the seller's policy. You are allowed to email the seller to get the details. Keep clicking on the seller's product section to find the contact link. BTW, this is a heavy duty pump. I had a tire with about 30# and within seconds, it got up to 36#. I recommend the VIAIR 300P.

**Q: I need to 'top off' my rv tires up to 125 psi. from anyone with experience... will this compressor work? if you don't know, please don't answer.**
A: Hello,

We recommend the 400P-Auto or 400P-RV since the 300P's gauge will only show up to 100psi.
Let us know if you have any other questions.

Thanks,
Viair Corp.

### ⭐⭐⭐⭐⭐ Compact and powerful
*by R***T on March 1, 2025*

This is a serious work horse. My hotdog compressor is rated for 150psi but can't inflate my 110psi fifth wheel tires! This little unit brought all four tires up to the recommended pressure in about ten minutes. It runs on 12volt power with big clamps directly to the battery so it works anywhere. It clamps onto the valve stem so you don't need bionic fingers to hold it on. It does get hot, but not dangerously. Highly recommend this for RV travel and nearly unlimited other uses.
